- Chromium 64.0.3282.119 which should include partial MP3 support.
- Fixed stability issues when you closed the browser due to circular interface references.
- Fixed TCefRTTIExtension thanks to Pier.
- Added the JSRTTIExtension demo to test TCefRTTIExtension.
- Added the TCustomResponseFilter class to filter the resource contents.
- Added the ResponseFilterBrowser demo to test the new TCustomResponseFilter class.
